APPARATUS FOR DRYING AND CONDlTlONlNG YARNS.

SPECIFICATION forming part of Letters Patent No. 718,770, dated January 20, 1903.

Application filed January 14, 1902. fierial No. 89,766. (No model.)

To ctZZ whom it may concern:

Be it known that We, JAMES KEITH, residing at 27 Farringdon avenue, and WILLIAM WIN- SHIP WARDLE, residing at 32 Somerfield road, Finsbury Park, London, England, citizens of the United Kingdom of Great Britain and Ireland, have invented certain new and useful Drying- Chambers and Apparatus for Drying and Conditioning Yarns, Fabrics, and other Goods, (for which application for patout has been made in Great Britain, No. 12,389, dated June 18, 1901,) of which the following is a specification.

This invention relates to drying-chambers and apparatus for heating and circulating air therethrough for the purpose of drying and conditioning yarns, fabrics, and other goods; and it comprises improvements in the construction and arrangement of such chambers and apparatus for conveying the goods through the drying-chambers while being acted on by the circulating air and for automatically delivering them, whereby the necessity for operators entering the heatingchambers is obviated.

In the accompanying drawings, which illustrate the invention, Figure 1 is a vertical longitudinal section, and Fig. 2 a vertical transverse section, of a drying and conditioning chamber and accessories constructed and arranged in accordance with the invention. Fig. 3 is a detail view of part of the conveying-band.

The arrangement hereinafter described is capable of drying fabrics, garments, and the like; but the devices for conveying the goods to be dried through the drying-chamber are particularly designed for holding hanks of yarn or other goods capable of being hung in loop form.

The drying-chamber 01, has vertical sides, and its roof is formed by a series of bays or sloping sides Z), according to the length of the chamber, the upper ends of these baysb resting on vertical walls 0, extending downward a short distance, so as to divide the upper portion of the chamber a into the same number of compartments as there are bays 1). In each of these vertical walls 0 a fan or fans 01 is or are located, arranged to discharge air under the sloping roofs b and down upon the goods to be dried, which goods are carried, as

hereinafter described, upon an endless traveling band 6, passing over rollers at either end of the compartment, said band being located in proximity to the lower end of the vertical walls 0. In some of these compartments heating apparatus, such as steam or hot-water pipes f, are situated, one set being arranged immediately above and parallel to the traveling band 6 and the other set in proximity'to the floor of the chamber a, others of the chamber being kept cool by the admission of cold air through an inlet, such as h, inlets such as a: being also provided for the admission of fresh air to the heated compartments. The air is circulated as shown by the arrows, being drawn upward by the fans (1 between the compartments and directed down under the sloping roofs through the goods onto the traveling band 6, the surplus or moist air being discharged by ventilators m in one of the roofs.

A door '5 is provided at one end of the chamber a, through which the hanks j of yarn or other goods may be placed upon the conveying-band e by the operator from the outside of said chamber, and a door Z is provided at the opposite end of the chamber a, through which the automatically-delivered goods may be periodically removed.

The delivery apparatus consists of a series of connected chain-links forming a pair of endless chains 6, passing over rollers k, capable of rotation to feed forward the goods, the chains being connected together, as shown particularly at Fig. 2, by cross-laths n, on each of which are a series of projecting pins 0 of such length as to fill the gaps between the lathsnand form a continuous or endless band. The hanksj are hung over the projecting pins 0 or over pairs of the pins, as shown, which project horizontally from the lath for the time being under the chain-rollerkat one end, and a forward movement is imparted to the endless chain e, which brings a fresh lath at under the roller is and close up to the pins 0,

' filled with the hanks j, thus locking the said pins 0. The 'pins 0 on this lath 'n are filled in like manner and the roller 70 again turned. At the opposite or delivery end of the drying-chamber a the roller k, carrying around the chain e and the laths n, brings the pins 0 on each lath a in succession into a vertical too position, as shown at Figs. 1 and 3, in which the hanksj are automatically released or drop ofi into receptacles 1), provided for their reception.

Having now described the invention, what we claim, and desire to sccu re by Letters Patent, is-

1. Means for drying and conditioning yarns, fabrics and other goods, comprising in combination a drying-chamber having a series of sloping roofs, a ventilator in one of said roofs, vertical walls dividing the upper portion of the chamber into compartments, fans located in said vertical walls, the side vertical walls of the dry-chamber having air-inlets therein on the discharge side of one of the fans, heating apparatus in proximity to said air-inlets and an endless-chain conveyor provided with pins adapted to carry the goods through the chamber in suspension and to automatically JAMES KEITH. WILLIAM WINSHIP WARDLE.
